AJAX & Search Engine Optimization (SEO)

I can make this quick. AJAX and SEO do not mix. Search engines can not read AJAX, because most search engines won't read most JavaScript. So when you implement AJAX, make sure to give search engines alternative methods of getting to the same content that is accessible via the AJAX form.

This shows an example of how Amazon is using an alternative to JavaScript for their users. But a search engine won't be able to index and crawl Amazon's non-AJAX version, because it is using image maps, forms and so on.

A good alternative would to design a linked based alternative that somehow has some of these filtering options.
